Chs4 insulator
WebJan 1, 2003 · The prototypic chromatin insulator cHS4 has proven effective in reducing silencing chromosomal position effects in a variety of settings. Most of this barrier insulator activity has been mapped to a 250-bp core region, as well as to several proteins that bind this region. However, recent studies from our laboratory demonstrated that an extended ...

WebSep 15, 2003 · The cHS4 insulator is located at the 5′ boundary between highly compacted chromatin and the transcriptionally active β-globin locus in chicken erythroid cells (1). Like other insulators, cHS4 blocks enhancer function on promoters and protects transgenes from position effects (2,3). WebAug 15, 2006 · The first vertebrate enhancer-blocking insulator to be identified was cHS4, a complex element that combines enhancer-blocking and barrier activity and lies at the 5′ end of the chicken β-globin ...
WebDec 22, 2012 · Chicken hypersensitive site-4 (cHS4) is one of the best-characterized vertebrate DNA insulators. Its barrier activity protects against position effects and enhances transgene expression. (Arumugam et al. 2007 ). A fragment of 250 bp (the core element) within cHS4 performs most of the insulating activity of the cHS4 insulator (Hanawa et al. … WebDec 3, 2013 · The cHS4 insulator gave similar colony and transgene copy numbers as the non-insulated control in the presence of transposase . However, the recombination control showed a higher colony number (Figure 5B, right panel) and 4-fold more insertions. Therefore, cHS4 may have insulator effect when copies are integrated by …
